Hi fellow users,
I have an issue with import of a particular epub file. It can be unpacked in 7zip and is readable in eBook Prestigio Android reader app without any issues and appears with its cover image. However, when I try to import it into Calibre by using manual add with the default import options, and try to open it in the viewer, I get these errors indicating the ZIP file is damaged and container.xml is missing (it is indeed missing, there is only one file called com.apple.ibooks.display-options.xml in META-INF folder, if renamed to container.xml then everything works fine except that no cover image appears as a result of import but it is visible in the Calibre viewer):

calibre, version 7.26.0

If I enable "Automatically convert added books to the preferred output format " and "When auto-converting, convert even if the format being added is the same as the output format" in Import/Export > Adding books preferences, Adding actions tab (default format being epub), I get these errors when importing:

It looks like Calibre isn't detecting com.apple.ibooks.display-options.xml as a valid container xml, but there is still a problem with extracting cover image file. Attached are com.apple.ibooks.display-options.xml renamed to contaner.xml and the repackaged with the renamed file epub book file

Cheers,
